Subthalamus

The subthalamic nucleus is a part of the midbrain ( diencephalon ), which is primarily responsible for the control of gross motor skills. The main structures of the subthalamic nucleus are the subthalamic nucleus and the globus pallidus, which operates as the center of the extrapyramidal system, is the antagonist to the corpus striatum and gross motor function in a larger pro-and a smaller motor function -inhibiting part is divided.

The subthalamic nucleus ( STN often abbreviated, older designations Corpus subthalamicum Luysi, Luys body ) is primarily with the globus pallidus in conjunction, from which it receives both signals and sends. He is hampered by the motor activity -promoting part of the pallidum and acts on the motor function -inhibiting part of the exciting pallidum (via glutamate ). Thus he takes on an important motion pulse inhibitory function.

Damage to the subthalamic nucleus leads to the clinical picture of ballism or unilateral failure to Hemiballism. Electrical stimulation of the STN by implanted microelectrodes can help to alleviate the symptoms of Parkinson 's disease ..
